Assume you are starting with a stock deck height (which vary anyway)
If you mill your heads to raise your comp, you will also need to shave the port faces to accomodate a STOCK intake. (I am sure you are onto this.. :thumbup: )
Any variation in the deck height or intake face angle and you have a bit of measuring to do...
BTW..I agree with your Cam recommendation...the Cranes make good torquey profiles in the smaller numbers......I'm suprised they don't get used more often in your part of the world... 8-)
